LAWRENCE, Kan. (AP) — Former U.S. Senators Nancy Kassebaum and Robert Dole said during a forum discussion at the University of Kansas that they lament the erosion of bipartisanship among political leaders in Washington. Dole and Kassebaum, both longtime Kansas Republicans, appeared Saturday at the Dole Institute of Politics at the University of Kansas. Dole, who is 93, served in the U.S. Senate from 1969 to 1996 and U.S. House from 1961 to 1969. Kassebaum, who served 18 years in the U.S. Senate with Dole, also Saturday received the 2016 Dole Leadership Prize, which is awarded annually to an individual or group whose public service inspired others. The Topeka Capital-Journal reports Dole said that he and Kassebaum understood that to get things done you have to work with colleagues outside your political party.
